IPhoto in 10.7.2 just killed a dozen family movies! :-(

Question

I just upgraded to 10.7.2 (with several problems: intermittent success in TimeCapsule backup, Mail program that won't accept my password and tells me I'm not conencted, but still sends and and received e-mails) but the latest glitch is particularly irritating.
Today I decided to import pictures and movies from my Canon PowerShot A710IS to iPhoto `09 V8.1.2(424).  After plugging the camera into my MacBook, iPhoto started up as usual and I went through the standard import menus and the import started.  Before the process could start iPhoto crashed.
After restarting iPhoto I got some messages that said it found the camera and had images to import and asked if I wanted to import them.  I clicked that I did and the import proceeded as usual.  Then, as usual, I deleted the pictures and movies from the camera after seeing that the import had gotten everything.
The thing is, it didn't get everything.  All to movies have the MVI_ name, but they are not movies, they are only images of the first frame of the movie and about half of the pictures are nowhere to be found, not on my camera and not on my computer.  Pictures from Hanukkah and Christmas.
Grrr.  Thanks Apple and 10.7.2!

Answer 1

Try the following to see if you can recover the photos without going back to the camera's memory stick:
Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot. 
Fix #2
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next  window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
If necessary you can recover the files from your camera's memory stick with software like  MediaRECOVER.  It can be run in demo mode to make sure it can recover what you need before purchasing it. 
Although the horse if out of the barn IMO the best method to upload from the camera is with a card reader uploading to a folder on the Desktop and import into iPhoto from there.  Then reformat the memory card with the camera.  This assures that the files are safely on the hard drive before any other action is taken.
Happy New Year
